[Abstract]:Based on the mechanism and characteristics of brittle material milling in plastic domain, the geometric model of micro-diameter ball end milling cutter is established, the instantaneous cutting thickness model is improved, and the analytic model of instantaneous milling force for brittle material milling is established by using reasonable micro-element model of cutting force. Using quartz glass as workpiece material, the experiment of ball end milling cutter micro-milling was carried out based on the improved experimental platform, and the experimental data of milling force were obtained, and the cutting force coefficient of the model was regressed. The model was verified and analyzed by experiments. The results show that the model has good applicability.
